PILE-WIRE -OILING DEVICE FOR LOOIVIS.

Specification of Letters Patent.

Patented April 9, 1907.

Application filed May 18, 1899. Renewed September 21, 1906. Serial No.335.649.

To all whom, it may concern:

Be it known that I, JOSEPH S. GILES, a citizen of the United States,residing at Worcester, in the county of Worcester and State ofMassachusetts, have invented a new and useful Oiling Device for Looms,of which the following is a specification.

The object of my present invention is to provide a simple, efficient,and inexpensive device for oiling pile-wires of looms.

To this end my invention consists of the parts and combinations ofparts, as hereinafter described, and more particularly pointed out inthe claims at the end of this specification.

In the accompanying drawings, Figure 1 is a plan view of sufficientparts of a loom to illustrate the application of my invention thereto.Fig. 2 is an enlarged detail view, partly in section, of an oilingdevice for looms constructed according to my invention. Fig. 3 is asimilar view showing the parts in a different relative position, andFig. 4 is a detail view illustrating the connections which may beemployed for turning the lubricating-wheel.

In weaving pile fabrics the wires on which the piles are formed have tobe successively withdrawn from the fabric, and when the fabric is of aclose texture or is beaten up comparatively hard a heavy pull isrequired to withdraw each successive wire. To facilitate this operation,it is now customary to provide an oiling device for lubricating eachwire as it is withdrawn, so that when said wire is again automaticallywoven into the fabric it may have sufficient oil thereon so that it canbe readily pulled or drawn out. While these oiling devices are anessential to the successful weaving of pile fabrics, great care has tobe exercised in using the same. This is especially true in weaving lightor delicately colored carpets. If an oiling device is arranged todeliver too great a quantity of oil to the wires, the surface of thecarpet is liable to show grease-spots or stains, and, on the other hand,if the wires are not sufficiently lubricated they will heat or becomestuck in the fabric, so as to be broken or cause the loom to beotherwise deranged. The especial object of my present invention is toinsure a more perfect distribution of oil and a more even lubrication ofthe wires by employing a lubricating-wheel having connections forturning the same so as to present fresh wearing-surfaces to the wire andinsure an efiicient oiling thereof. The lubricating-wheel preferably hasa portion of its periphery cut away, and connections are preferablyprovided for normally holding the lubricating-wheel in position to leavea clear path for the hook which is employed for catching and withdrawingthe wires, and connections are employed so that as each wire iswithdrawn the wheel will be turned or oscillated so as to bring itsperiphery into engagement with the wire to oil the same.

A further object of my present invention is to provide an oiling deviceconstructed so that surplus oil will run back into the can and will notbe allowed to drip or run down so as to be liable to injure the fabricbeing woven.

Referring to the drawings and in detail, A designates the loom side; B,the vibrating lathe; C, the sword; D, the reed, and E the picker-stick.tion of these parts is so well understood that it is not thoughtnecessary to describe the same at length in this specification.

F designates a carriage, which may be reciprocated in the usualmanneras, for ex ample, by means of a link G, connected to the upper endof the vibrating lever H. Extending from the carriage F is the hook 10for catching and withdrawing the wires 11.

The oiling device, as herein illustrated, is

.supported by any ordinary bracket extending in from the loom side andconsists of a can or receptacle 12, having a cover 13 fitting downinside the upper end thereof. The cover 13 is provided with a flaringdrip-flange 14, and in practice I have found this to be a desirablearrangement, as the surplus oil collected by the drip-flange 14 is notliable to run out of the joint between the can 12 and its cover 13.Extending from the can up through the cover thereof are one or morestrands of wicking 15. Journaled in arms extending up from the can 12 isa lubricatingwheel 16. The lubricating-wheel 16 preferably has itssurface formed of felt or other capillary material, and the periphery ofthe wheel 16 is slab'bed or cut away, as shown. To hold thelubricating-wheel 16 in position to leave a free path of movement forthe hook 10, which catches and withdraws the wires, I preferably providea flexible connection or cord, which extends up through the hub of thelubricating-wheel and is provided at its lower end with a weight 18.Coiled or wound upon the hub of the lubricating-wheel is a flexible cordor connection 19, which is connected to the lever H, as shown mostclearly in Fig. 4.

The operation of an oiling device as thus constructed is asfollows: Whenthe carriage F is moved to bring the hook 10 into engagement with a wire11 for the purpose of catching and withdrawing the same, the cord orconnection 19 will be loosened and the weight 18 will hold thelubricating-wheel 16 in its normal position, (illustrated in Fig. 2,)leaving a clear path of movement for the hook 10 and the end piece ofthe wire 11, which is being withdrawn. As a wire is being pulled out ofthe fabric the flexible cord or connection 19 will be tightened and thelubricating-wheel 16 will be turned to bring itsperiphery intoengagement with the body portion of the wire 11, as shown in Fig. 2.

The connections for operating the lubricating-wheel are preferablyarranged so that its peripheral speed is somewhat less than the speed oftravel of the wire 11 which is being withdrawn, so that although thewheel 16 is turned to present difi erent portions of its surface to thebottom of the wire 11 at the same time the wire 11 will slip to acertain extent on the surface of the lubricatingwheel, insuring an evenlubrication thereof. Furthermore, by means of this construction theamount of oil delivered to each of the wires 11 may be regulated oradjusted by tightening or changing the point to which the cord 19 isconnected to the lever H, so as to cause the lubricating-wheel to beturned to a greater or less extent, as desired.

I am aware that numerous changes may be made in the construction of myoiling device for looms by those skilled in the art, and I do not wish,therefore, to be limited to the construction or proportions which I haveherein shown and described; but

I/Vhat I do claim, and desire to secure by Letters Patent of the UnitedStates, is

1. In a loom, the combination of the wires, the hook for catching andWithdrawing the same, a lubricating-wheel having its periphery cut awayto clear the hook, and means for I turning the lubricating-wheel tobring its periphery into engagement with the wires, sub

3. In a loom, the combination of the wires,

the hook for catching and withdrawing the same, a lubricating-wheelhaving its periphery partly cut away, a weight for normally holding thewheel in position to clear the hook, and a flexible connection forturning the wheel to engage the wires, substantially as described.

4. In a loom, the combination of the wires, the hook for catching andwithdrawing the same, a lever connected to operate the hook, an oilingdevice comprising a reservoir or can, a lubricating-wheel having a partof its periphery cut away, wicking for supplying oil from the can to theperiphery of the lubrieating-wheel, a weight connected to normally holdthe lubricating-wheel in position to clear the hook, and a flexible cordor connection extending from the lubricating- Wheel to the lever whichoperates the hook for turning said lubricating-wheel to engage thewires, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing Witnesses.
